To all whom it may concern:

@Be it known that L'WrnmAM GEORGE lVIsE, a subject of the King of Great,

Britain, residing at New 'York city, in the county of New York and State, of New York,

have invented new and useful Improve-v ments in' Can Openers, of whichthe following 1s a specification.

theme of expensive dies, and which will not require the expensive assembling operation usual where such openers are secured clirec-tly to the can.

With these and other objects in view,

which will bemore apparent as the specification proceeds, the invention resides in combination and arrangement of parts, the

essential features-of which are hereinafter fully described, are particularly'pointed out in the appended claims,and are illustrated Figure 1 is a side elevation partly in sec tion of a can showing the opener in place Figure 2 is a similar view with the opener turned to effective position. i

They have also been of a more or or less delicate character, apt to get out of order or be broken, and have formed'object-ionable projections on the eficiency' in handlmg and packing. j Furthermore they have effected a spreading of the cover flange y so thatafter opening and closing a few They have I all boxes which all deto my attention a secured to the can, w-hicl Dart upon beingturnedhas come into contact with "a single eifecting the desired result."

usual lateral annular bead The bottom section is pro 12; and the top section 11 is providednear V the top of its flange 13 with a similar lateral annular head 14:. The bead 14 strengthens and stiffens flange 13 andvalsoexerts a ten sion which tends to force the edge of the flange inwardly if anyslight distortion is; i if effected in 1 opening thebox, whereby the flange 13 will always remain a snug fit for the bottom.

The openerproper is a tack15 of'elliptical Y cross-section the minor diameter of which is less than the distance between beads'12 and l l lfwhen, the box is closed, and themajor diameter of which is equal to or greater than the distance between the saidbeads when the edges of the box sections are in the same horizontalplane. The tack 15 is provided 7 with a fiat rearface-from which extend; two

points or spurs 16 preferably located at jop-i posite ends of the tack head. The "pur f pose of having two spurs is to secure the tack in place and also to prevent its turning When put under strain When in use. The front face of the tack head is curved in Wardly at an arc to conform with contour of the side of the box. This tack will be given to the purchaser of the box, and he will aflix the tack in the end of his shoe brush 17 Where it will always be found When wanted, and Where the brush will form a handle for giving the necessary leverage for performing the opening operation.

It will be readily seen that by inserting the tack head 15 between the flanges 12 and 14 of the can and then turning the brush in either direction, the lid will be easily and positively removed from the box or can.

While I have described What I deem to be the most desirable embodiment of my invention, it is obvious that many of the details may be varied Withoutin any Way departing from the spirit of my invention, and I therefore do not limit myself to the exact the curved 'ein set forth nor WllOle of my indetails 0 t0 anyt ventionl y j What 1. a lower 1 the upper and withlat l and an elliptical opening 7; front face curved to confo f of said container and pr ardly projecting spurs fo 's hoe brush as and forthe in V e 2.
